Engineering Data

CNI’s General Engineering Data catalog-brochure provides a process (formulas) for the determination of Resistance Coefficient K, Equivalent Length L/D, and Flow Coefficient Cv. Pressure loss test data for a wide variety of valves and fittings. Extensive studies in this field have been conducted by Crane Laboratories, but since not every possible configuration is cited in our catalogs, it is desirable to provide a means of reliably extrapolating available test information for items which have not been or cannot readily be tested.
